Scale Finder

A scale is a set of notes arranged in ascending or descending order. Modes are scales derived from the degrees of a parent scale. For example, the seven modes (Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian) are all built from the Major scale but start on different degrees, giving each mode a unique character and interval pattern.

Diatonic chords are triads built using only the notes within a specific scale. For a 7-note scale, you get 7 diatonic chords — one starting on each scale degree. The quality of each chord (Major, Minor, Diminished, or Augmented) is determined by the intervals between its notes within the scale.

For example, in C Major scale, the diatonic triads are: C (I), Dm (ii), Em (iii), F (IV), G (V), Am (vi), and Bdim (vii°).

Diatonic chord analysis works with 7-note scales that follow traditional harmonic patterns. Scales with fewer notes (like Pentatonic with 5 or Blues with 6) or more notes (like Diminished with 8 or Chromatic with 12) don't follow the standard diatonic chord-building pattern, so chord analysis is not displayed for these scale types.

• Notes: Shows the letter name of each note (C, D, E...). Best for beginners learning note positions on the fretboard.
• Degrees: Shows the position within the scale (1, 2, b3...). Useful for understanding scale structure and recognizing patterns across different keys.
• Intervals: Shows the quality and distance from the root (P1 = Perfect Unison, M2 = Major 2nd, m3 = Minor 3rd, etc.). Helps with ear training and advanced theory analysis.

Sharp (♯) and flat (♭) are two ways to name the same pitches. C# and Db sound identical — they are enharmonic equivalents. The choice between sharp and flat notation often depends on the musical context: sharp keys tend to use sharps, while flat keys tend to use flats. This tool lets you switch freely between both notations.

In music theory, choosing the correct enharmonic spelling helps maintain consistent interval relationships and makes reading music easier. For example, in the key of E major, we use D# (not Eb) to maintain the pattern of letter names.

Audio is synthesized directly in your browser using the Web Audio API. No sound files are downloaded or streamed. The tool generates sine wave tones at the correct frequency for each note (based on A4 = 440 Hz standard tuning) with a natural-sounding envelope for attack and decay.

Yes. The fretboard display shows all positions where scale notes appear in standard tuning (E A D G B E) across 15 frets. You can click individual fret positions to hear each note and verify your fingering. Switch to Degrees or Intervals mode to deepen your understanding of scale patterns on the neck.

Practice Tips:

• Start by learning one position (5 frets) at a time
• Use Degrees mode to recognize movable patterns
• Practice connecting adjacent positions for full-neck coverage
• Use the audio playback to train your ear while visualizing patterns
• Compare related scales to understand modal fingerings
